JAMES MCWHORTER, OF BLOOMING GROVE, INDIANA.

MACHINE FOR MAKING COOPERS HOOPS OUT OF SPLIT TIMBER.

Specification of Iietters Patent No. 3,328, dated November 6, 1843.

To all fwz-om t may concern:

Be it known that I, JAMEs MCWHORTER, of Blooming Grove, in the county ofFranklin and State of Indiana, have invented a new and useful Manner ofConstructing a Machine for `llIaking Goopers Hoops Out of Split Timber;and I -do hereby declare that the following is a full and exactdescription thereof.

This machine consists in part, of a bench which may be four feet long,and onefoot wide, more or less, and has suitable legs, or standards, tosustain it at a proper height.

\ Upon the bench is placed two knives, or cutters, one of 4which is'toshave, or cut, the lower, and the other the upper side of the splitstuff the knife which is to cut the upper side ofthe hoop is to be soformed as to finish it either flat or rounding as may be desired.`Between these knives there is a pressing and guide roller, which is tobe borne` down by springs, or weights, upon the split, 'from which thehoop is to be formed. In front` of the bench there is a wheel, or drum,around which the hoop is to coil as it escapes from the cutting knives.This drum is furnished with pincers which are made to grip one end ofthis split, when by turning a winch it is drawn along and dressed by theknives; the shaft of the drum has a screw formed on one of its ends,which screw is tapped into one of the legs of the machine, and as thedrum revolves, it is thereby made to move laterally so as to wind thedressed hoop spirally on its periphery.

In the accompanying drawings, Figure l, is a side elevation, `and Fig.2, a top view of the machine.

A, A, is the bench which has the knives attached to it; one of theseknives is shown at B, Fig. l, affixed in place by a wedge in the mannerof a plane iron.

C, is a plate of metal making a part of the throat through which theshaving is to pass.`

This knife is to split flat.

D, is the knife which is to cutthe upper side of the hoop, and thecutting edge of this may be either flat, or curved, so as to make arounding hoop.

E, are set screws by which the knifeD, may be regulated.

cut the underside of the revolves in sliding standards G, G, that passthrough` mortises in the bench A. This roller is shown as drawn down bysprings H. The sliding standards G, may be raised by means of the leverJ; for this purpose the foot may be placed on the iron rod, or treadleJ, attached toit.

I, I, are screws for regulating the tension of the springs H. The wheelVF, instead of being borne down by springs, as represented, may be madeto raise and lower in slots in the standardsG, G, and be borne down byweighted levers.

K, is the wheel, or drum, around which the .hoop is to be coiled as itis dressed by the knives.

L, L, are pinions which are to hold one end of the split, said splitbeing first passed under the pressing roller F, and under the knife D,its end being reduced for that purpose.

M, M, is the shaft of the drum K, its screw end M, passing through afemale` screw in the leg N, of the bench.

O, is a shaft which runs, and slides laterally, in bearings in `theupper `ends, of the legs, or standards N, N. This shaft is turned by awinch I), and carries a` toothed wheel, or pinion Q, that mashes into atoothed wheel R, R, afIiXed to one side of the drum. A circular plate ofmetal, S is` made fast on one side of the pinion Q, and projects beyondits teeth. This plate enters a groove T, between the drum and the wheelR, and in consequence of this arrange ment, as the shaft O, is turned to,give motion to the drum K, the shaft O, slides inits bearings, andfollows the lateral motion of the drum, produced bythe action of thescrew M', and the dressed hoop consequently is coiled upon the drum.

Having thus fully described the nature and actionof my machine, formaking coopers hoops out of split timber, what I claim therein as new,and desire to secure by Letters Patent, is-

` The manner of arranging and combining the drum K, with its screw shaftand pincers with the sliding shaft G, with its pinion, and plate, S, soas by their joint action todraw the split forward, and cause the dressedhoop to wind around the drum; said drum and its appendages being alsocombined with the cutting, or dressing appatus, so as to constitute amachine substantially the same with that herein described. F, is thepressing and guide roller, which` J AMES MCIVHORTER.
